School prepares children for work of adult life by indoctrinating them into blindly following orders and eliminating critical thought, to do as your told, no matter how ridiculous. The education offered is mostly one of punctuality, sitting still, stifling daydreams of freedom, attempts to kill hope, and the free spirit. The very things one ACTUALLY needs to succeed and set yourself apart. They want cogs in a wheel, uniformity, not individuals, nor entrepreneurs.

The children are taught the hypocrisy inherent in the system at an early age as the powers that be condemn drugs whilst simultaneously over prescribing prescription drugs to those very children to stop them from acting like children.
1. Drugs are bad, don't do drugs
2. Take these drugs because you run around and talk too much
Moral: Corporate profits are more important than a normal childhood

No more suffering, no more pain
